Effect of water stress and salicylic acid on some quantitative characteristics of mung bean

Environmental stresses (drought, salinity, heat, cold, etc.) represent a major constraint to meeting the world food demand, which effect of drought, affecting 45% loss in crop yield, is of considerable importance. Among the favorable characters of growing Mung bean, fast growth, nitrogen fixation capability and prevention of soil erosion are in top. Salicylic acid (SA) is a plant origin phenolic compound that has shown its role as a growth enhancer. The experiment was conducted at the Research Station tropical fruits and natural resources in bahukalat (In Iran). The field experiment was laid out in randomized complete block design with split plot design with three replications. Analysis of variance showed that the effect of water stress and salicylic acid on quantitative characteristics was significant.
